CEEG Box-type Substation PV Inverter Boosting Device

CEEG is aligning with industry development and policy trends to address customer needs. Leveraging its robust research and production capabilities, CEPC has introduced the Intelligent Integrated Photovoltaic Inverter Boosting System to collaborate with customers in furthering cost reduction and efficiency enhancement, thereby supporting grid parity in the photovoltaic sector.

The Containerized Integrated Photovoltaic Inverter Grid-Connection System (referred to as the Integrated System) is a complete photovoltaic grid-connection system operating at 0.4~35KV with three-phase alternating current at 50Hz. This system integrates photovoltaic grid-connected inverters, transformers, high and low-voltage switchgear, enclosures, and other equipment into a single unit. It realizes functions such as direct current distribution, inversion and grid connection, boosting, alternating current distribution, and intelligent communication monitoring for photovoltaic power plants. This product can replace the traditional "MW house + photovoltaic box transformer" model and is widely used in distributed and centralized photovoltaic power plants, meeting the requirements of standards such as GB 17467, NB/T 32004, GB1094.11, GB 7251.1, and GB 3906.

1. Turnkey Solution:

a. Integration of photovoltaic inverters, transformers, and switchgear, factory-tested as a whole, saving on-site installation and commissioning time.

b. The enclosure is designed as a container, eliminating the need for specialized lifting equipment, and making transportation and installation convenient.

2. Strong Environmental Adaptability:

a. Strong corrosion resistance: The enclosure is of container type and made of highly weather-resistant steel plate, which offers superior corrosion resistance compared to standard carbon steel.

b. Thermal insulation: Insulation boards are installed inside the enclosure, providing excellent fire resistance, heat insulation, and thermal insulation.

c. Effective ventilation and heat dissipation: The intake vents are specially designed to effectively prevent dust and sand intrusion.

3. High Reliability and Safety:

a. Use of epoxy resin cast dry-type transformers, which are flame-retardant products, eliminating the risk of explosions and fires.

b. Dry-type transformers have passed C2, E2, and F1 tests conducted by the National Transformer Quality Supervision and Inspection Center.

4. Cost-Effective with High Returns:

a. Compared to the conventional "inverter room + photovoltaic box transformer" setup, it reduces investment by 15%~20%.

b. Reduction in the number of installation foundations from 2 to 1.

50% savings in installation and commissioning time.

Copper connections between inverters and transformers reduce the need for cables between the inverter room and the photovoltaic box transformer. Structural optimization saves on two low-voltage switchgear units between the inverter and transformer.

5. Flexible and Diverse Product Solutions:

Product solutions can be tailored to meet the specific needs of customers, providing a one-stop solution that satisfies their requirements.
